Ultratrace quantities of transuranic actinides are detected indirectly by their effect on the fluorescent emissions of a preselected fluorescent species. Transuranic actinides in a sample are coprecipitated with a host lattice material containing at least one preselected fluorescent species. The actinide...http://www.google.com.au/patents/US4724217?utm_source=gb-gplus-sharePatent US4724217 - Ultratrace analysis of transuranic actinides by laser-induced fluorescence
